Abstract: A flow restrictor includes an exterior tube and an interior tube disposed within the exterior tube. A first flange is disposed at a distal end of the interior tube. An annular rib extends proximally from the first flange and has an interior diameter greater than an exterior diameter of the exterior tube. A second flange is disposed at a proximal end of the exterior tube. A ring member is disposed around the exterior tube between the annular rib of the first flange and the second flange.

Abstract: The management and analysis of events of communications environments are facilitated. Events, such as alert and network events, are separated into a plurality of pools, depending on the classification of event. Each pool has events exclusive of one type of event. The events are placed in the appropriate pools via one or more analysis routines. Additionally, events of at least one type of pool are further analyzed using one or more analysis routines to determine which events, if any, are to be reported.

Abstract: A series of state transitions is indicative of performance of hardware service actions. A transition from, for instance, a disconnected state to a connected state for a hardware component is indicative of performance of a service action for the hardware component. Detection of this transition is automatic.

Abstract: Network managers are operated in verification mode to facilitate error handling of communications networks. In verification mode, error reporting remains enabled, even for those components of a communications network reporting errors. A step-by-step procedure is provided for handling each type of error that is detected. Subsequent to handling any reported errors, the network manager is removed from verification mode and may be placed in production mode.

Abstract: A fully integrated drying or heating system utilizes forced air and electrical heaters. A solid cartridge heater is enclosed within a heater cavity of a block. The block includes a separate air cavity in heat transfer communication with the heater through a solid portion of the block. The blocks are shaped and configured to be used in banks of plural blocks, with the operating controls and all the components of the air distribution system and air heating system fully integrated into a modular package.

Abstract: A vent assembly or breathing tube adapted to relieve pressure in an axle assembly or other gear housing. A vent tube may be disposed within a casing and terminates at an oblique or circular open end in a skirt portion of the tube. At least one hole may extend through the side of the casing to allow pressurized gases within the housing to escape through the vent tube via the oblique opening. The casing has a hole disposed at the bottom surface to allow the return of any lubricant which might enter the casing through the side hole. The side hole is preferably located on a side opposite the lubricant flow direction. The neck portion may be integrally formed with the top portion and skirt.

Abstract: The present invention is directed to a vent assembly or breathing tube adapted to relieve pressure in an axle assembly or other gear housing. A vent tube is disposed within a casing and terminates at a non-truncated oblique open end. At least one hole extends through the side of the casing to allow pressurized gases within the housing to escape through the vent tube via the oblique opening. The casing has a hole disposed on a substantially closed bottom surface to allow the return of any lubricant which might enter the casing through the side hole. The side hole is preferably located on a side opposite the side facing the oblique opening.

Abstract: An enhanced single frame buffer video display system is described for combining both video and graphical images. A single frame buffer is implemented which stores a single data format for pixel types which may be interpreted by a conventional video generator for output to conventional color graphics computer display devices. The system utilizes an enhanced graphics controller which does all pixel processing for translating all incoming graphics and video data to a single format type as well as performing, blending and scaling. The system is readily scalable for handling additional format data types.
